It was incompetent with a sinister undertone. Mohammed Reveshi, aka Rez had a longstanding beef with Don Fraser one of the detectives investigating the case. Rez and Fraser were neighbours and Rez was said to have had a fling with Fraser's wife.
Iyad Albattikkhi, aka Eddie, Rez's business partner in the kebab shop fell out with Tariq his brother. After 3 years with no results a half baked plan came about when Tariq told the police he heard Eddie saying he killed Charlene and put her body into kebabs. Don Fraser sent David Cassiday, a petty criminal who owed the shop owners a lot of money to record them.
Eddie & Rez have a long list of allegations of inappropriate behaviour around females, especially younger ones. Bad men but not killers. No one would miss them if they went to prison, Cassiday wouldn't need to pay his debt & could claim the £100000 reward, Fraser would have revenge on Rez and look good solving the case.
It was a disaster, Cassiday had no experience of surveillance and recording, the tapes were virtually useless. They were transcribed by Jan Beassant an officer with no experience of recording to make it look like the kebab men had admitted their guilt. The case against them was twice dismissed as the tapes were so bad they were inadmissable.
Meanwhile the far right EDL & BNP had come on board and the ridiculous kebab story was believed. Eddie & Rez were each given £250000 compensation for wrongful arrest.
The manpower, time and money wasted allowed the real killer to escape justice. The family enjoyed the support of the far right til the social service files came to light and they were very quickly dropped. It says much about the family when men like Tommy Robinson & Nick Griffin washed their hands of them!
The family still persist in the kebab story (there would have been a ton of DNA in the shophad it been true). CSI tore the shop apart and found nothing, I lived nearby and saw it.The family has lost a lot of support as people realise the wrongdoing going on in the home and they have refused to cooperate with the police or answer any of the allegations in the reports.
Also 109 Buchanan Street was initially searched as a missing person inquiry. A full forensic CSI search was never done
